Cool, thanks jimbo & Chris. I probably should've just opened my EF3 up before I installed it, but this was easier.

On a side note, I've had my EF3 on my car for a week now - I'm loving every mile of it.

 

Been a long time coming, but these are just the beginning numbers.
Heres the specs:
Curt Brown Spec 2.3ltr motor 10.5:1
Curt Brown built head, Kelford 280 cams
MAP EF4
C16
Single Walbro 255lph, 1450cc inj., Stock fuel rail LOL
31 PSI in 3rd gear
Tuned by Jay@TPG Tuning
VERY low reading Mustang Dyno


There was a pull after this netting 612whp SAE Corrected. This is more than 650 on a Dynojet.

Will be running this in a 2500-2600ish lb car with slicks tomorrow. Keep you guys posted.

 

How are you only running a single walbro 255?

 

Because its C16 and not E85. A single wally with race gas can support 600-700hp.

 

I think I may have asked you this before, but are you still on the 6-speed? I highly doubt it, but figure I should ask.

 

What weight was used on the dyno, 2600 or the typical 3600 most use on dyno days?

 

Yep. Will eventually go to E85/E98, but still have to do a complete fuel overhaul.
HELL NO. That junk melted down at 60k miles. Been on a Shep 5spd with stock final drive for over 30k miles now.
That's a good question. I'm really not sure. All I know is it reads lower than pretty much everyone else.

*Update: Went to Import Faceoff and got a whole 3 passes in before weather ended my day. Conditions were typically terrible for Pittsburgh this time of year: 90 degrees with 90% humidity. Track elevation 1300ft. I bogged off the line all three times and couldn't do any better than a 1.8 60ft. Best pass was an embarrassing 11.30@134 with granny shifting and I hit fuel cut before the traps - probably would have trapped 137.

Car rips and I'm still confident it will do solid 9s with a 1.4-1.5 60ft. I just need to knock the rust off as it was my first pass on this setup and first time driving the car in a year and a half. To be continued...

 

What size is the compressor intake on the EF4??

 

Well, it went faster!

that mph is dead on with hp on a mustang vs your cars weight. now you just have to learn the ef4 like you did the stock turbo to get your 9 second pass. nice job so far though. 144 is really moving on a stock frame turbo off the shelf 9 second pass is in your near future it looks like.

 

Excellent job Sir, that track must have been hooking the truck ran as quick as it could per his mph awesome runs

 

Looks like this needs to be updated!

well I finally signed a lease on a house which means I can actually start driving my car again instead of having it just sit in a storage unit. I need to eventually get to a track to get some times with my EF3, but I'll wait until the weather cools off. Not much fun going down the track at 100*F

good to see some numbers from other people

 

Well, on the 10.2 pass, I cut a 1.71 60ft due to over inflation of the tires and spinning/lifting out of the hole. We dropped the psi down to 18 and on the next pass I cut a 1.47 60ft...slammed second like a boss, .2 seconds faster at the 330 mark...then 3rd decided that I was going too fast for it's liking and said NO.

So, that was the single digit pass right there. I think my 3rd gear is messed up. Won't go into gear at high rpm. Ordering underhood and base shifter bushings to see if it will alleviate the problem, but I don't have high hopes. Clio tells me I have a second tranny build in my future.

Going to also try short shifting 3rd next time. Was VERY frustrated and settling with the 10.2 was bittersweet knowing that the 9 second pass was only two shifts away. I'll figure out how to squeek a 9 second pass in there one way or another...it's definitely got the cojones to do it!

 

Well, it went a little faster. Still won't be satisfied until I get that 9 second pass, but we're getting there. Looks like I'm going to need a refreshed tranny after all . https://www.evolutionm.net/forums/dr...n-quicker.html
